God only knows, and I mean that literally.  Certainly these sorts of things were tweaked during development.

I would put in a logging statement to see what the value actually is at runtime, if you really need to know.

Subject: [theora-dev] 35 max entropy tokens

<p>Hi,
        Here is something that confused me greatly at first. In Huffman.h,
the comment "35" sits above the definition of MAX_ENTROPY_TOKENS:

// 35
#define MAX_ENTROPY_TOKENS      (DCT_RUN_CATEGORY2 + 2)

Yet, if you do math from all the preceding #defines (not easy given that
each in a long chain of #defines is defined in terms of the previous
#define), there are actually 32 tokens.

        Were there originally 35 tokens? Just curious...
